Description

[Detailed description of the invention] [Industrial application field]

This invention relates to a duct type air conditioner that can independently adjust the room temperature of each room.

[Conventional technology]

Conventionally, in a duct type air conditioner employing a variable air flow system (VAV), a damper was installed in each room to adjust the airflow as follows. The first is, for example, as shown in Japanese Unexamined Patent Publication No. 57-196029, a diaphragm-type air volume adjustment unit is placed in each part of the duct connected to the thermal iIftm, and a damper control unit that is not installed in each room is used. By the signal of the thermostat,
The opening degree of the damper in the airflow adjustment unit is adjusted so that the air flow is appropriate for the heat load. The second type is, for example, as shown in Japanese Patent Application Laid-open No. 50-91937, in which the heat source unit and each room are connected by a duct shaped like a kite, and a damper is provided in the air outlet at the end of the duct. . Note that the damper can also be placed in the middle of the octopus-like duct. The third method is, for example, the method shown in Japanese Patent Publication No. 50-37456, in which a necessary number of dampers are built into the heat pump, and ducts are connected from these to each room in a telescope pattern. In all of the above-mentioned conventional systems, the capacity of the blower in the heat source unit is adjusted, for example by controlling the rotation speed, so that the air pressure upstream of the damper is almost constant, and the temperature of the air being blown is adjusted. The capacity of the heat exchanger of the heat source device is controlled and adjusted so that the temperature remains almost constant.

[Problems to be solved by the invention]

The first of the conventional air conditioners mentioned above has a long distance between the heat+1'ii unit and each air volume control unit, which means that the electrical wiring work has to be done and the units are installed in the ceiling. There was a problem in that it was necessary to install an inspection port corresponding to each unit on the ceiling surface, and that it was difficult to install an inspection port in a one-story residential building. The second problem, like the first, is that the electrical wiring work is troublesome, and since the air volume is greatly restricted at the duct outlet, noise is generated due to pressure loss, and this noise is transmitted directly into the room. There was a point. Furthermore, the third one is the first one. Although the second problem can be solved, it is necessary to change the design of the number of dampers in the heat source machine depending on the number of rooms to be air conditioned, or to build in many dampers in advance, and it is necessary to install a large plenum inside the heat source machine. There was a problem in that a chamber had to be provided. The object of the present invention is to solve the above-mentioned problems and provide an air conditioner in which installation of a wind foot adjustment unit and wiring work are easy, and there is no restriction on the number of rooms to be air conditioned.

[Means to solve the problem]

In the air conditioner according to the present invention, at the outlet connection port of the heat source device,
Wind j! has a damper for adjusting the wind shortness and a motor that moves it wX! The adjustment units are connected in sequence, these units are connected to each room by a duct, and the opening degree of the damper is controlled by a thermostat installed in each room.

[For use]

In the air conditioner according to the present invention, by sequentially connecting the wind i adjustment units according to the number of rooms to the outlet connection ports of the heat source device, it is possible to freely correspond to the number of rooms to be air-conditioned, and the degree of freedom is high. can configure a large individual air conditioning system.

【Example】

FIG. 1 is a configuration explanatory diagram showing an embodiment of the present invention. In the figure, 1 is a heat source device, and the heat source device 1 includes a heat exchanger 2 connected to a beat pump (not shown), a blower 2a,
It has a filter 3 and a blowout connection port 4. Reference numeral 5 designates li number of wind foot adjustment units that are sequentially connected to the outlet connection ports 4 of the heat source device 1, and these units 5 are installed in the center of the horizontal duct 6 and communicate with the horizontal duct 6, which is open at both ends. The vertical duct 7 forms a T-shaped duct. 8 is a fitting part provided at one end of the horizontal duct 6;
The fitting portion 8 connects the horizontal ducts 6 to each other, or connects the outlet connection port 4 to the horizontal duct 6. 10 is a stepping motor for controlling the opening degree of the damper 9. 11 is an end plate that closes the open end of the horizontal duct 6 of the air volume adjustment unit 5 connected to the end, 12
13 is a flexible circular cross-section duct connected to the tip opening of the vertical duct 7; 13 is an air outlet connected to the tip of the duct 12 and attached to the ceiling 16a of the room 16;
Reference numeral 14 designates a fresh air suction port provided at the bottom of the door 17 of section i16, and reference numeral 15 designates a room thermostat installed in the room 16, which is connected to the motor 10 via a control device (not shown). The air conditioner configured as described above can be adapted to various construction cases by sequentially connecting the air volume adjustment units 5 according to the number of rooms to be air conditioned. Note that the installation location of the heat source unit 1 and the wind i adjustment unit 5 can be freely selected such as a machine room or the ceiling. Damper 9 for adjusting air flow rate
The control is to turn on the motor 10 so that the room temperature detected by the room thermostat 15 becomes the preset room temperature,
OFF control, or the control device changes the opening degree of the damper 9 using the motor 10 according to the difference between the set value and the room temperature.
Control room temperature by changing the texture. In addition, zA source Ia
1 is controlled by ON/OFF or capacity control so that the humidity of the supplied air becomes almost constant according to the total amount of air flowing through each duct 12. Further, the rotation of the blower 2a is controlled so that the pressure within the horizontal duct 6 is approximately constant. Then, by operating the blower 2a, the air that has passed through the heat exchanger 2 and been conditioned is subjected to FX'kkiA knots by each damper 9, is sent through the duct 12 to the outlet 13, and is blown out into the room 16. The air in the room 16 is conditioned, and the air flows from the inlet 14 through the hallway and returns to the heat source device 1. In the above-mentioned embodiment, the diameter of the horizontal duct 6 of each wind section unit 5 was made the same, but several diameters are prepared, and the diameter is gradually increased as the distance from the machine 1 increases. The horizontal duct 6 may be connected so that it becomes narrower, and even if this is done, the air volume will gradually decrease as the distance increases, so the pressure loss will not increase.Also, in the above embodiment, the air volume adjustment unit Although the aperture type is used, this may be a bypass type.Furthermore, in addition to the above-mentioned heat source device 1, it is also possible to use a device integrated with a heat pump, a furnace, etc. ] As explained above, this invention has a simple configuration in which the air volume adjustment units are successively connected to the outlet connection port of the #A source unit, which facilitates wiring work and can flexibly accommodate the number of rooms to be air-conditioned. It is possible to achieve the effect of easily performing individual air conditioning.
